Upstream has deprecated the non-SQL database backend from Aodh, and they are going away. They also provide a script to migrate the alarms contained in MongoDB to SQL backends.

Verified according test plan.
Unless the documentation explicitly talks about MongoDB for Aodh, I don't think there's anything to update in the documentation.
